Problems solved by technology

Due to the small size of the wood core, it is not suitable for processing. It is often discarded as waste or used as firewood. The added value is low, which not only affects the environment but also reduces the utilization rate of wood. It does not meet the requirements of deep processing of wood and environmental protection requirements.
There are also some used for the production of glulam. The glulam produced is made of quadrilateral single-layer gluing. The main problems are: the material utilization rate is low, which can only reach about 45%; the glulam products are mainly boards, and the product specifications Small, severe deformation, narrow application range

Embodiment 1

[0026] The glulam 1 with a honeycomb structure is formed by gluing hexagonal wood strips 2 arranged in a honeycomb shape. Hexagonal wood strips are leftover wood cores from plywood production and small-diameter logs with a diameter of less than 6 cm; leftover wood cores from plywood production and small-diameter logs with a diameter of less than 6 cm are planed and sawn into hexagonal wood sticks after drying; Part of the hexagonal strips are cut diagonally to form trapezoidal strips 3 for filling up the gaps in the hexagonal rear edges; Fill up the pentagonal wooden strips 4 of the hexagonal rear edge gaps, the hexagonal wooden strips are glued together in a honeycomb arrangement, the trapezoidal wooden strips 3 and the pentagonal wooden strips 4 The outer side of the glulam with a honeycomb structure, the glulam with a honeycomb structure forms a finished glulam with a square shape.

Embodiment 2

[0028] A method for producing glulam with a honeycomb structure, comprising the following steps:

[0029] (1) Collect the remaining wood cores from plywood production and small-diameter logs with a diameter of less than 6cm;

[0030] (2) Carry out drying treatment, dry the wood core or small-diameter logs according to conventional methods, and control the moisture content at 8-12%;

[0031] (3) Cutting: Cut the dried wood core or small diameter log into a uniform length according to the conventional method;

[0032] (4) Slicing: slice the wood core or small-diameter logs into hexagonal wood strips 2, and part of the hexagonal wood strips are cut diagonally into trapezoidal wood strips for filling the edge gaps after the hexagonal arrangement 3; Some hexagonal wooden strips are bisected along the midpoint of the opposite side to form a pentagonal wooden strip 4 for filling the edge gap after the hexagonal arrangement, which is used to fill the four-sided gap when forming blank...

Abstract

The invention discloses cellular-structure laminated wood which is formed by arranging and gluing hexagonal battens cellularly. The invention further provides a production method of the cellular-structure laminated wood. The cellular-structure laminated wood and the production method have the advantages that wooden cores or small-diameter logs are directly planed and cut to be hexagonal, and utilization rate can reach 82%; the hexagonal battens are arranged and glued cellularly, and gluing faces are distributed in three directions in a 120-degree included angle manner, eliminating of deformation of the battens is facilitated, and stability and gluing strength of the laminated wood are improved; the hexagonal battens can be arranged cellularly and glued to be the laminated wood various in size, and can be further integrated in the length direction in a toothing connection, large-size laminated wood can be freely sawn transversely, and needs, on the laminated wood different in specification, of users are met.

Description

technical field [0001] The invention relates to a production process for making wood cores and other small-diameter logs into honeycomb-shaped laminated materials, especially the forming, gluing and integration processes of hexagonal wood strips. It belongs to the field of wood processing and wood comprehensive utilization. Background technique [0002] At present, there are a large number of processing residues produced in the production process of plywood in my country - the wood core (wooden round rod) left after the wood veneer is peeled, and the logging residues and Qingshan residues with a diameter of less than 6cm. between 6cm. Due to the small size of the wood core, it is not suitable for processing. It is often discarded as waste or used as firewood. The added value is low, which not only affects the environment but also reduces the utilization rate of wood. There are also some used for the production of glulam. The glulam produced is made of quadrilateral single-l...
